Looking for a simple, warranty-friendly upgrade for your car? The VWR High-Flow Panel Air Filters, available for most Volkswagen Group TSI and TDI cars replace the restrictive factory paper filters with an improved, high flow and reusable lifetime triple-layer Trifoam® filter. Put simply, it’s the best Panel Air Filter you can buy.The filter is one of the most cost-effective enhancements you can make to set your engine free by allowing it to breathe better and operate more efficiently – improve the engine’s airflow, and power and fuel economy gains will follow. By removing the inevitable restrictions that the standard paper panel filter gives, the VWR Panel Filter allows a small but worthwhile increase in airflow through to the turbo. A great match for a Stage 1 OEM+ remap or a standard car.The result? More mid-range power and improved economy, without wrecking your warranty.
